Troubleshooting Indoor
Domes
CAUTION:
This troubleshooting section is for
indoor camera domes only! To troubleshoot
outdoor domes, see installation and service
manual shipped with the outdoor housing.
This chapter contains information on:
•
Routine troubleshooting
•
Detailed
troubleshooting
•
Disassembling the dome.
IMPORTANT!
1. Try routine troubleshooting first! Use this
procedure to isolate the problem without
disassembling the housing and eyeball
assembly (the base with the I/O board is
field repairable).
CAUTION:
DO NOT troubleshoot if the dome
functions but does not pan or tilt (see step 2).
2. If you cannot isolate the problem, or the dome
functions but does not pan or tilt, contact your
sales representative for repair instructions.
3. If you have no choice but to repair the housing
and eyeball assembly. Follow the detailed
troubleshooting procedure, but use extreme
care.
CAUTION:
Once disassembled, parts of the
housing and eyeball assembly are "extremely
fragile" and may break. Proceed using extreme
care!
Items You Will Need
You should have on hand the following items:
•
Phillips-head
screwdriver
•
Small
slotted
screwdriver
•
2.5mm (0.1in) slotted screwdriver (for wire
connections). Wider blade widths can damage
connectors.
•
Socket wrench with 5in extension and 5.5mm,
6mm, 8mm, and 10mm sockets
•
14-18 AWG and 20-22 AWG wire strippers
•
Install/Removal tool to connect/disconnect
dome to indoor bases with I/O boards, and to
attach/detach skirts and bubbles—without a
ladder.
Routine Troubleshooting
Use this procedure if:
•
Dome does not respond to commands
•
Dome does not produce video
•
Quality of the video is poor
•
Dome has no lens control.
CAUTION:
•
DO NOT use this procedure if the dome
functions but does not pan or tilt (see step 2 on
page 22).
•
If an I/O board is used, use a ground strap
when handling the board. When shipping a
base having an I/O board, place the dust cover
over the spring finger connector to protect it.
•
DO NOT over tighten connector screws on the
I/O board; they are delicate. Use a 2.5mm
(0.1in) slotted screwdriver. Wider blade widths
can damage connectors.
